downflow and vertical applications.
• Multi-speed — Gives flexibility of installation.
• Ease-of-Service — Plug-in wire connections and builtin
filter rack makes the air handler easy to service.
• Plug-in Heater Kits —Available in 5kw - 30 kw
(Not for use in 115 Volt units)
• Circuit Board — Incorporating blower time delay relay,
low voltage terminal strip, and heat-strip sequencing.
• Air Handler Control Board — Controls time-sequencing
of heat stages with field-selectable sequence timing.
• Breaker Accessibility — Breaker accessible from front
of unit when heater is applied.
• No Fasteners on Sides or Back — Smooth surfaces for
ease of installation.
• Warranty — Five year limited all parts warranty, a major
benefit to the consumer.
